> Microsoft 365 technical leadership | Wieger Bosgraaf

    Microsoft 365 Tech Lead at a.s.r.

    Microsoft 365 needs more than administration. It needs technical leadership.

    I help make complex Microsoft 365 environments governable, secure and ready for Copilot. I write and speak about governance, security, platform operations and the decisions required to lead Microsoft 365 as a business-critical product.

    What I believe

    Three principles for a governable platform

    01

    Governance is an operating model

    Not a policy document, but a working system of ownership, decision-making, controls and feedback.

    02

    Copilot readiness starts before licensing

    Identity, permissions, information quality and ownership determine whether AI can scale responsibly.

    03

    Microsoft 365 is a business-critical product

    The tenant needs a roadmap, product leadership and technical direction across teams, vendors and admin portals.

    Technical leadership

    Microsoft 365 needs more than administration. It needs technical leadership

    A tenant can be technically operational while becoming organisationally unmanageable. The difference lies in ownership, coherence and decision quality.
